Nitecore NU40 High Performance Lightweight USB-C rechargeable Headlamp - 1000 Lumens w/ Eco-Sensa USB-C Charging cable



The NITECORE NU40 High Performance Lightweight USB-C Rechargeable Headlamp has an innovative design of the built-in 18650 Li-ion battery that features light weight and high capacity, achieving the perfect combination of lightweight, long runtime and outstanding output.


Thanks to an optimized intelligent charging solution, it only takes 1.5 hours to fully charge the NU40, which significantly  saves the wait time. What's more, the ultra-low standby power consumption allows a 365-day ready experience in the standby status.


The NU40 can produce a max output of 1,000 lumens, ideal for way finding and searching at night. Utilizing a unibody optical lens system with a light transmission of over 94%, the NU40 is specially designed for reflecting uniform and soft light while it features TrueVision+ Technology ideal for road observing and signage searching.


With an overall weight of 116g (4.09 oz), the NU40 is designed with a combined structure and is constructed from stamped aluminum alloy front housing and special PC plastic rear housing, which is a perfect fusion of high strength, comfort and lightweight. Powered by the built-in 2,600mAh 18650 Li-ion battery, it can provide 10 hours max runtime on 100 lumens MID Level, ensuring stable output throughout the night.


The included skin friendly widened headband is designed with the concealed silicone strip to divert sweat to the sides of the head and avoid sliding of the headband. The near-center of gravity bracket greatly reduces the pressure on the forehead from the lower edge of the bracket without shaking during intense exercise while it is 72° all-round adjustable and one-hand operable, applicable to avoid direct lighting on staff in aid stations.


The dual buttons interface allows for straightforward operation — long press the Power Button for 1 second to turn it on / off. The NU40 is also available with direct access to Red Light or ULTRALOW Level.


Equipped with multiple protection safeguards — sensor protection function, transportation guarantee and lockout mode, the NU40 is IP68 rated and 2m impact resistant, ideal for trail running, trekking, camping, cycling and more.
